Detailed Description

Applies sources on k and either epsilon or omega to prevent them droping below a specified ambient value for atmospheric boundary layer modelling. Such adjustment reportedly increases numerical stability for very stable atmospheric stability conditions, and prevents nonphysical oscillations in regions of low shear at higher altitudes.

Corrections applied to:

  k         | Turbulent kinetic energy                  [m2/s2]

Corrections applied to either of the below, if exist:

  epsilon   | Turbulent kinetic energy dissipation rate [m2/s3]
  omega     | Specific dissipation rate                 [1/s]

Required fields:

  k             | Turbulent kinetic energy                    [m2/s2]
  epsilon/omega | Dissipation rate OR Spec. dissipation rate  [m2/s3]/[1/s]

Usage

Example by using constant/fvOptions:

atmAmbientTurbSource1
{
    // Mandatory entries (unmodifiable)
    type                  atmAmbientTurbSource;

    atmAmbientTurbSourceCoeffs
    {
        // Mandatory (inherited) entries (unmodifiable)
        selectionMode    all;

        // Mandatory entries (unmodifiable)
        kAmb              0.0;

        // Optional entries (unmodifiable)
        rho               rho;
        epsilonAmb        0.0;
        omegaAmb          0.0;
    }

    // Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Req'd	Dflt
`type`	Type name: atmAmbientTurbSource	word	yes	-
`kAmb`	Ambient value for `k`	scalar	yes	-
`rho`	Name of density field	word	no	rho
`epsilonAmb`	Ambient value for `epsilon`	scalar	no	0.0
`omegaAmb`	Ambient value for `omega`	scalar	no	0.0
